Winter 7 FMS serie Einbau- Und Wartungsanweisung

INSTALLATION INSTRUCTIONS
The mounting dimensions of the pitot airspeed indicator correspond to the so-called small standard.
The diameter of the hole in the instrument panel is 57 mm, the hole circle diameter on the mounting
flange is 67 mm. M 4 countersunk screws are used for fastening. The instrument panel should be flat
and fixing holes should be accurately located for stress-free mounting of the instrument. The
instrument panel should be well sprung.
The airspeed indicator must be connected to the total pressure (measured pressure) and the static
pressure; static pressure is tapped either from the second connection of the pitot tube or by static
pressure sensors attached to the fuselage sides. The pressure tapping point should be selected so
that no errors are produced from air flow around the aircraft fuselage.
Hose leads should be as short as possible and must not be twisted or contain sharp bends. Kinking of
hoses should be avoided in all cases. Hoses and connections must be absolutely leak-tight. The
instruments must be protected from water penetration. If the hose from the pressure tapping points
cannot be run upwards, a water trap (waterbag) should be fitted at the lowest point.
Before putting into service, a test must be carried out for leak-tightness. If the aircraft manufacturer has
not given any special instructions for this, our standard instruction for leak-thightness testing, January
1978 edition, can be used.
MAINTENANCE INSTRUCTIONS
Leak testing should be carried out at least every 2 years. Otherwise, the instument dose not require any
maintenance.
We recommend that airspeed indicators are subjected to retesting after 5 years.
RETESTING AND REPAIR
The service condition and accuracy of measurement of the altimeter is normally retained over a long
period. For obvious malfunction the unit should be subjected to an investigation at the manufacturer
or a suitable aircraft engineering company. It should be packed to protect it from impacts and
connections should be sealed. Under no circumstances should you interfere with the measuring
mechaism of the airspeed indicator.
